The temperature for furnace brazing typically ranges between 500°C and 1200°C. This wide temperature range accommodates various materials and filler metals used in brazing processes. The specific temperature within this range is chosen based on the melting point of the filler metal and the compatibility of the base materials.
The process begins by gradually increasing the furnace temperature to the selected brazing temperature. This slow ramp-up helps in proper heat distribution across the parts being joined and minimizes thermal stresses that could lead to distortion or damage. Once the brazing temperature is reached, it is maintained for a specific duration. This time allows the filler metal to melt, flow into the joint, and wet the surfaces of the base metals, ensuring a strong and reliable bond.
After the brazing process, the furnace is cooled slowly to room temperature. This controlled cooling phase is crucial to prevent thermal shock and further reduce the risk of distortion or cracking in the materials. Once cooled, the parts are inspected to ensure the quality of the brazed joints meets the required standards. Depending on the application, post-brazing treatments such as heat treatment, machining, or surface finishing may be applied to enhance the properties or appearance of the brazed components.
In furnace brazing, the environment within the furnace is also critical. The atmosphere is typically controlled to have a low dew point (≤ -40°C) and low oxygen content (< 100 ppm), often using inert gases like nitrogen. This controlled environment helps prevent oxidation and other chemical reactions that could degrade the quality of the brazed joints.
In summary, furnace brazing is performed at temperatures between 500°C and 1200°C, depending on the specific materials and filler metals involved. The process involves careful control of heating and cooling rates, as well as the furnace atmosphere, to ensure the integrity and quality of the brazed joints.
